本幻灯片演示概述了监管信息、指南和建议 以及一项调查 五个完整的配电系统（DSs）中消毒副产物（DBPs）的形成和衰变。 本文还介绍了选择DS的决策工具 监测现场是否符合第2阶段消毒剂/消毒副产品规则（DBPR）。涵盖的主题包括:第2阶段DBPR的四个关键组成部分；初始分配系统评估（IDSE）；系统分类和IDSE计划； IDSE选项:标准监控程序 （SMP）或系统特定研究（SSS）；SMP采样位置；SMP采样时间表；使用历史DBP数据的SSS；使用水DS模型的SSS；使用替代方案的SSS；IDSE报告；AwwaRF/USEPA项目2770的主要目标- “DS中DBP的形成和衰变”；选择参与系统、采样地点；以及这项研究的主要发现。

This slide presentation outlines regulatory information, guidance and key results from a study investigating the formation and decay of disinfection byproducts (DBPs) in five full-scale distribution systems (DSs). This paper also presents decision tools to select DS monitoring sites to comply with the Stage 2 Disinfectants/Disinfection Byproduct Rule (DBPR). Topics covered include: the four key components of the Stage 2 DBPR; initial distribution system evaluation (IDSE); System Classification and IDSE Schedule; IDSE Options: Standard Monitoring Program (SMP) or System-Specific Study (SSS); SMP sampling locations; schedule of SMP sampling; SSS using historic DBP data; SSS using water DS model; SSS using alternative options; reporting for IDSE; key objectives of AwwaRF/USEPA Project 2770 - "Formation and Decay of DBPs in the DS"; selection of participating systems, sampling locations; and, key findings of the study.
